How are mined blocks broadcasted in a distributed environment?

How are mined blocks broadcasted in a distributed environment?

I understand that after the golden nonce is found by the miner he broadcasts the block and the other miners verify it. But I don't understand how they broadcast it because bitcoin is completely distributed with no servers to store the ip to distribute it to. How does a new miner know whom to distribute it to?

Any help is really appreciated ...

bitcoin node: what is the difference between simnet and regtest?

bitcoin node: what is the difference between simnet and regtest? btcd, and presumably other bitcoin node implementations, seem to have 4 network options: mainnet testnet regtest simnet. I get that mainnet and testnet both are "public" in that your node will communicate with other nodes and that both have an existing blockchain and genesis block. However, from what I can tell, both simenet and regtest both create a local only blockchain, and both will create a new genesis block. I this case, what is the difference, and which is better (easier) for developing bitcoin applications? This is what the documentation has to say: --regtest Use the regression test network --simnet Use the simulation test network https://ift.tt/2TAMkwe

How to check if Electrum is masking my IP with the Tor proxy?

How to check if Electrum is masking my IP with the Tor proxy? When i start Electrum from the command line i see this mensage: (python3:7069): dbind-WARNING **: 14:09:58.452: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken What does it mean? I just installed Electrum following this tutorial: http://docs.electrum.org/en/latest/tor.html I followed the instructions from this topic " Option 2: Multiple servers but Tor Main ". I installed Electrum using the command line on Ubuntu, check the " Installation from Python sources " on this link https://electrum.org/#download if you want to see the codes. And i used this code bellow to download the Signatue keys: $ gpg --keyserver pool.sks-keyservers.net --recv-keys 2BD5824B7F9470E6 I checked the both checkbox: 1)...

How generic miner connects to bitcoin or ethereum network and does it needs to store entire blockchain?

How generic miner connects to bitcoin or ethereum network and does it needs to store entire blockchain? Suppose I want to design generic crypto currency miner starting from scratch . By generic I mean it can be configured to support a large number of available crypto currencies. How this miner knows to mine coins for bitcoin as opposed to ethereum coin (ETH), for example ? For ethereum it will connect to etherium P2P network and what is the network address OR there are some kind of API exposed by ethereum network which it invokes? Assume this generic miner directly connects to crypto currency network for the purpose of mining coins without mining pools. Does it needs to store entire blockchain of the crypto currency in local disk storage? The answers to above questions do not depend on wether the miner is configured to use CPU or GPU or both? http://ift.tt/2Dv1cYY
